>Description:
My friends found that comping net/nagios-base which requires perl>=5.6 
(according to net/nagios-base/Makefile.common) deletes lang/perl5 package even 
when the version of installed perl is 5.8.8nb4.

>How-To-Repeat:
At CVS HEAD of pkgsrc, install lang/perl5 and try to compile net/nagios-base.
>Fix:
net/nagios-base/Makefile.common has the requirement that perl>=5.6, and 
net/nagios-base/Makefile includes ../../lang/perl5/buildlink3.mk.  On the other 
hand, lang/perl5/buildlink3.mk adds the requirement that perl>=5.8.7.  So at 
this moment, PERL5_REQD=5.6 5.8.7, but no file includes lang/perl5/version.mk, 
therefore pkgsrc system cannot resolve dependencies correctly.

Maybe lang/perl5/buildlink3.mk or something should includes 
lang/perl5/version.mk, I guess?
